Specification forming part of Letters Patent No. l 73,284, datedFebruary 8, 1876; application filed i December 7, 1875.

To all whom it may 'concern Be it knownsthat I, CHARLES H. HELMs, ofPoughkeepsie, in the State of New York, have invented an ImprovedEdge-Setter,` of which the following is a specification, reference beinghad to the accompanying drawings making a part hereof.

My machine is extremely simple, and consists of a head or standardcarryinga toolholder, holding a tool for setting' or burnishing theedges of the soles of boots and shoes, and a linger-restto aid theworkman in holdin g the edge up to the tool, and the face of the soleagainst the rest, which is just below the burnishin g part of the tool.

The drawings represent the best form of my machine, A being the head, Bthe toolholder, G the tool, and D the finger-rest. The tool-holder B isfast to a slide, F, which is reciprocated by an eccentric pin, @on theshaft G. This pin, to prevent Wear, is journaled in the small slide b,which reciprocates in a slot in the slide F. This slide F is mounted inways formed by the parts c and d of the head, as shown in thedrawings.The part cV of the head is in practice made adjustable so that it can bepressed closely against the ver- 'lhe tnger-rest D is ahooked-shapedpiece secured to the head near the tool, as s'hown -in the drawings. Forcouvenienceit is mounted upon a tang, which is held by a set-screw. Itshould be vmode of some non-conductor of heat, or else be wrapped withsome non-conducting wrapper. The tool is heated by means of steam, whichenters the upper part of the head by means of pipes g g', one an inletthe other an outlet pipe. The ,head is cored out for this purpose, asindicated in the drawings, fbeing Steam is not essential,

as the friction of the tool heats it considera. bly, but is desirablefor the best work. The toolholder is backed up by a spring, h. The

tool may be in one piece, with a tang which lits the holder, or may besecured in a proper socket at the lower part of this tang. In practicethe latter modev is used, as shown in Figs 3 and 4.

I The operation is as follows: The workman holds the shoe firmly in hishands, and thus presents the edge to be burnished to the tool, whichreciprocates with great rapidity-about one thousand eight hundred timesper minutc, I nd, gives the best results. 4man passes the edge upagainst the tool, and the face of the sole against the surface whichprojects below the tool, and gradually moves the shoe so as to bring allparts of the edge to its action, steadying the shoe by the Vaid of thefinger-rest D, `especially when burnishing the corners of the toes. Alittle experience is necessary to enable the workman to use the machineto great advantage, but a skilled workman can do a very large quantityof work second to none in quality.

The combination of the finger-rest D with the burnishing-tool, and therest for the face of the sole, is the main feature of my invention. Allthe other points of novelty in my machine also relate to newcombinations of old elements.

What I claim as my invention is l. In combination with theburnishing-tool and the rest for the face ofthe sole, the ngerrest D,substantially as described.

2. The combination of the finger-rest D, the

burnishing-tool, and the elastic tool-holder B,

as set forth.

3. The burnishing-tool, its holder B, slide F, ways c and d, shaft Gr,and .pin a, all combined together as specified. Y
